Just looking for code snippets to remove color from jpg image.
I would like to remove red, blue, green from a picture, leaving black and white. For instance, imagine a newspaper cartoon with an "X" on the picture. I want to remove the colors leaving the "X". I'd also like to have Jscrollpanel show with original image and one with new image next to it (two JScrollPanes on same screen) so I can see what is happening ans I progress.
Thanks in advance.
